摘要

Published data are reviewed on the physicochemical characteristics and biokinetic behaviour of radionuclides that may influence the calculation of radiation doses following their release into the environment after a nuclear accident or incident. Among the important parameters which can influence the assessment of dose coefficients (doses per unit intake), four main Parameters can be measured: the particle size distribution of aerosols: the isotopic composition; the dissolution parameters such As in vitro dissolution rates or in vivo absorption parameters to blood. Which are the most relevant in terms of inhalation; and The gastrointestinal absorption factor, f_1, for ingestion.
